Mayo Clinic "singing surgeons" Dr. Elvis Francois and Dr. William Robinson will provide a unique tribute to fellow frontline health care workers as part of Sunday's "Indy 500 Special: Back Home Again" broadcast airing at 2 p.m. EDT on NBC.

The doctors' performance will also help to raise awareness of The Fight Is In Us, an important campaign to encourage survivors of COVID-19 to donate potentially life-saving plasma for research into new treatments for COVID-19.

Dr. Francois and Dr. Robinson, both orthopedic surgery residents at Mayo Clinic, have performed for patients for several years, delivering emotional support alongside medical treatment to those in need.

"We're honored to be part of this special broadcast from racing's most iconic venue," Dr. Francois said. "Seeing so many of my colleagues and front-line workers across the country come together in the midst of such challenging times has been inspiring. This performance is dedicated to everyone who keeps showing up in the fight against COVID-19.

"Our performance is very much about hope," Dr. Robinson said. "It's important to remember that we’re all in this together and we’re all working tirelessly toward the same goal. Despite the current hardships, there is definitely reason for optimism, and we hope that our rendition of 'God Bless America' will reflect this mindset."
